地图扫描影像中文字、符号注记的自动提取

Automatic Extracting of the Text and Symbol Annotation in Map Scanning Image

地图扫描影像中的文字、符号注记与图形目标的分离是实现地图符号注记自动识别的重要前提和基础。文中提出一种基于影像行的连接影像目标整体及交互的提取压法、借助该算法不仅可以有效地实现地图扫描影像中文字、符号注记与图形线划目标的分离，而且可以实现其它一些二值影像的处理及分析。

Separating the symbol and text from the graphic objects in scanned map image is an important condition and foundation for automatically realizing the recognitionof map.symbol and text. In this paper, an image-line-based algorithm for separatingsymbol and text from the graphic objects in scanned map image has been provided.This algorithm not only can be used to separate symbol and text from other graphic objects, but also can be used to realise some other processing and analyzing functions binary image.
